 Trustindex verifies that the original source of the review is Google. Mike and Ryan installed our central AC and ADU mini-split a few weeks ago. Overall, a fantastic and smooth experience. Mike was incredibly patient with my many HVAC questions and stands behind his work! The mechanical inspector noted their work looked top notch and did a clean installation.

They went above and beyond to ensure the concrete pad was shored up with an extra wood slat and minimal sheet rock cuts to run electrical from our utility room to the crawl space. Would highly recommend to anyone who is looking for either central AC or mini splits. Thank you Mike and Ryan - we’ve been staying cool this summer!

 Trustindex verifies that the original source of the review is Google. We are very happy with the installation of a heat pump through Cloud 9. Looking for HVAC installation is extremely stressful, and Brent was considerate and patient with his explanations of the process.  A big reason we went with Cloud 9 was because of their installation. They were not rushed and weren't just "slamming in" a new heat pump in less than a day to move onto a new project. They took their time so that they could provide a high quality installation with attention to detail. The whole team of Brent, Mike, and Ryan were really great to work with!

 Trustindex verifies that the original source of the review is Google. I hired Cloud 9 to do my heat pump installation on my house. These guys came as a recommendation and I was very impressed all the way around with them. Hands down these were my favorite contractors I've worked with to date. Excellent communication, and punctual! Brent was easy to work with and Mike and Ryan were also super nice and fantastic - the entire team knows what they're doing. (Also these guys came in at the lowest bid!)  Would hire them again for install and will be using them to service my heat pump in the future. (And yes, Brent is right.. you DO want the Mitsubishi Hyper Heat! - the thing is incredible)

 Trustindex verifies that the original source of the review is Google. I had a great experience working with Brent at Cloud 9 during the quote process. He was incredibly honest, flexible, and truly focused on finding the best solution for our needs rather than just making a sale. He took the time to explain my options and answer my questions to ensure we understood what would work best for our home at the right price!

 Trustindex verifies that the original source of the review is Google. Brent from Could9  provided a reasonable $$$ and professional proposal he also gave detailed explanation of work that needed to be done.  They discussed my needs and help me make a choice on a Mitsubishi heating and air system for my house.  Mike came and assessed one more time before the work started. They installed the air handler and duct work in the attic for my SFR. Mike Ryan and Brent were extremely nice and willing to explain as the install was happening.   I made the right decision using Cloud9.   I am very happy and would recommend them for heating and cooling needs.

 Trustindex verifies that the original source of the review is Google. Within the past 3 months I have had Brent and his team install both a new hot water heater and a new Mitsubishi heat pump at my house. I am extremely happy with both. Brent is great to work with - he is both responsive and flexible. The quotes / rates he provided were super competitive. His team of installers are great guys and did exceptional work. I have already referred Brent to several friends and family members and highly recommend Cloud 9 to anyone looking for HVAC services or a new hot water heater. I can assure you, you will be very pleased!

 Trustindex verifies that the original source of the review is Google. Brent and his crew of installers, Mike and Ryan, were exceptional in their work replacing our oil furnace with a Mitsubishi Heat Pump system. Brent was highly communicative, transparent and honest. Mike and Ryan were personal and professional and made the install process seem like easy work. I highly recommend Cloud 9 to anyone looking for HVAc services and I will definitely use them again in the future.

 Trustindex verifies that the original source of the review is Google. I just called Brent and Mike and they spent the time on the phone with me to diagnose my problem and advise me as much as possible over the phone. This is totally different from the company that actually installed my unit (zero help, terrible availability, no empathy). I will definitely be using this company in the future for the upgrade. Thank you so much, Cloud 9.
